Application filedDecember 8, 1917. Serial No. 206,277.

To all whom it may concern:

Be it known that'I, ORvILLE O. SHELINE, a citizen of the United States, and resident of-Chicago, in thecounty of Cook and State of Illinois, have invented new and useful Improvements in Receptacles, of which the following is a specification.

This invention relates to receptacles and more particularly topaper receptacles designed for use as sputum flasks. ,7 The-principal'object of the invention is toproduce' a flask which; can be cheaply and readily constructed, which will rigidly hold together after being assembled, which is preferably formed from a single sheet of material, which has improved means for locking the end portionsto- 'the side portions after the sheet of material has been foldedinto the desired form of receptacle, which preferably has bellows endsjand whichhas an exceedingly 'tight and close fitting cover, the cover preferablybeing arranged to cooperatewith the locking means .Fig. 2 is a similar view showing the blank partially folded to form the receptacle;

Fig.- 3 is a similar view showing an advanced-stage of the folding operation;

Fig. 4 is a similar view, parts being broken away, showinga still. further stage ofthe folding operations Fig. 5 is asimi further stage;

' Fig. 6 is asimilar View. showing astill further stage. I

Fig. 7 is a similar view showing the re ceptacle completely assembled, with the ends extending outwardly, and having its cover raised; v T

Fig. 8 is aview identical with Fig, 7, except that the endsof the receptacle are folded inwardly into normal position, the receptacle being partly compressed together;

Fig. 9. is a front elevationof the recep v tacle in closed condition;

Fig. 10 is a vertical central section of the receptacle in completely assembled but opened position; and

Fig. llflis a-vertical central section, tal'zen lar view showing a still on line 11-11 of Fig. 9, showing the receptacle in closed condition.

While the structure of my improved receptacle may take any one of many forms within'the scope of the present invention as defined by the appended claims, it is pref- 3 and 4: adapted to be folded along the back portion, portions 5 and 6. which form the bellowsends of the receptacle when assem bled, parts '7 and 8 which are intended to be folded along the front portion 2, portions 9 and 10 forming integral extensions of portions 6 and 7 and lockingcertain parts together as hereinafter described, portions 11 and 12 which are preferably formed as an integral extension of one of the lateral portions 3, and the cover comprising portions 13, 1 1, 15 and 16. After the blankshown in. Fig. 1 has been stamped out, or at the same time as the blank is being cut out,it is preferably scored along the lines shown in Fig. 1 so that it may be folded along these lines. I

After the blank has been stamped and scored it is preferably folded together in substantially the following manner: The left-hand portion 3 is foldedinwardly along. the inside of back portion 1, as shown in Fig. 2, the left-hand portion, is then folded outwardly along theleft-hand portion 3, the portion 4 being shown in a position slightly. in advance of its final position in Fig. 3, and the right-hand portion 3 is then folded over the left-hand portions 3 and l, the right hand portion 3 being moved partly into position in Fig. 3. When the parts 3 and l have been placed in their final position they lie against each otherand against the back 7 portion 1, eachportion being parallel to the back portion 1, as shown for example in the" the portions'3and 4:, as shown in The flap 12 at one side of the extension 11 is then folded under the right-hand members 3 and 4, as shown in Fig. 5, it being understood that the parts are suliiciently flexible to allow them to be sprung somewhat. After the flap 12 has been placed in this position the parts 3 and are held together and the parts are also held against the back 1.

After the back portion of the receptacle has been folded together in the above described manner, the front portion is assembled in the following manner, although it is possible to assemble the front portion before the rear portion. The portion 8 is folded inwardly along the inside of the front 2 and the portion 7 is folded outwardly along the portion 8 as shown in Fig. 6. These three parts, namely, parts 7, 8 and 2, are then compressed together so that they lie in pan allelism, and the front 2 is flexed so that its upper edge is substantially in alinement with the upper edge of section 6. The extension 9-1O on parts (3 and 7 may then be folded outwardly along the line between" parts 9 and 10, and parts 6 and 7 over the part 8 and the front :2. Then by allowing the front 2 to flex outwardly into normal position the extension 9-10 is bent about the line between the parts 9 and 10, as shown in Fig. 7, on which position the extension 9-10 cannot be folded upwardly but is locked in position. The manner of locking parts 9 and 10 over parts 7, 8 and 2 is the same for both sides, so that the above description will explain the manner of securing both sides together. The receptacle now is in the condition shown in Fig. 7. The ends 5 and 6 are then folded inwardly instead of outwardly as shown in Fig. 8, and the recep tacle is in completely assembled condition.

In order to close the receptacle the front and back are pressed together and the cover is folded forwardly over the top of the receptacle, which is comparatively narrow as shown in Fig. 11. The base 13 of the cover is positioned over the mouth of the receptacle as shown in Fig. 11 and the portions 14, 15 and 16 function to hold the base of the cover in this position, the portion 1% folding downwardly along the front 2 and the portion 15 folding upwardly into the pockets or recesses under the portions 10 of the locking extensions 910. The tab 16, which is struck-up from the portion 15 of the cover, extends downwardly as shown in Fig. 9 and affords means whereby the portion 15 may be conveniently pulled out from under the portions 10 to uncover the receptacle. As shown in Figs. 10 and 11, the ends of the receptacle comprise parts 5, 6, and 17, the parts 5 and 6 folding inwardly so as notto be visible when the receptacle is closed. The end portion 17 is preferably scored along its vertical center line, as is also the bottom 18, so that the receptacle when in closed position may be tightly pressed together so as to occupy a very small space. However, it is to be understood that the scoring in the ends 17 and the bottom 18 may be omitted and that the ends 17 and bottom 18 may be as narrow as desired, it being possible to make them of negligible width.

A receptacle having the novel characteristics recited in the appended claims is exceedingly easy and inexpensive to construct, it being formed completely of a single piece of paper or other suitable material, the parts are tightly locked together, the receptacle can be extended at the top by virtue of the bellows ends 5 and 6, and the cover can be tightly and quickly secured over the mouth of the receptacle so as to render the device practically non-spillable.

I claim:

1. A, receptacle one side of which comprises a central portion and two lateral portions folded inwardly along the central portion, and a flap on one of said lateral portions folded over one of the other portions and then folded under one of said portions so as to hold the portions together.

l. A receptacle comprising a central wall portion, two lateral wall portions, at least one of said lateral wall portions being folded inwardly and then outwardly along the central Wall portion and the other lateral portion being folded inwardly along the central portion, and a flap on thelatter portion foldmg over and then under the other lateral portion so as to hold the portions together.

5. A receptacle comprising a central portion and two lateral portions connected to opposite sides of the central portion, each of the lateral portions being folded inwardly and then outwardly along the central portion, and a flap on one of said lateral portions folded over and then under the other lateral portion so as to hold the portions together. i

u 6. A receptacle comprising a central portion and two lateral portions connected to opposite sides of the central portion, each of the lateral portions being folded inwardly and then outwardly along the central portion, and a flap on one lateral portion folded over and then under the other lateral portion, the axis of the second foldof the flap being substantially collinear with the axis of the second fold of the other lateral portion.

7. A receptacle comprising a central portion and two lateral portions connected to opposite sides of the central portion, each of the lateral portions being folded inwardly and then outwardly along the central por-- tion, the axes about which each lateral portion is folded being oblique to each other, and a flap on one lateral portion folded over and then under the other lateral portion, the axis of the second fold of the flap being substantially collinear with the axis of the second fold of the other lateral portion.

8. A receptacle comprising a central portion, two triangular lateral portions each folded along the central portion about one of its sides, a flap on the other side of one of the lateral portions folded over and then under the other lateral portion, the second fold of the flap being over and around the hypotenuse of the other lateral portion.

9. A receptaclecomprising a substantially rectangular central portion, two substantially rectangular lateral portions connected to opposite sides of the central portion, the lateral portions being folded inwardly along the opposite sides of the central portion and then outwardly about axes oblique to the opposite sides of the central portion respec-' tively, and a flap on one of the portions folded over the lateral portions and around the oblique axis of one of the lateral portions so as to hold the portions together.

10. A receptacle comprising two adjacent wall portions folded together and an extension on one of theportions folded over the first fold about an axis transverse of the first fold to hold the two portions together.

11. A receptacle comprising two integral walls meeting at a corner, one wall having a fold extending along the other wall, and an extension on one wall extending on both sides of said corner folded over said fold to hold the fold against the other wall.
